Left 4 Dead 2

Custom Campaign select screen: - Show all installed custom campaigns, not just the ones that support the current mode. - Disable list items for campaigns that don't support the current mode, and sort them to the bottom of the list. - Fixed some uninitialized text fields when no campaign is selected. - Moved an informational string so it doesn't overlap the campaign list.

Workshop Publishing Tool: - Removed the file count from the download progress bar to avoid confusion when stale meta-data indicates there are more files than actually exist. - Don't show the download progress bar if no valid files were found. - Fixed the "Failed to write file chunk…" error message not correctly showing the number of bytes written.

As if slaying your way across a zombie-infested wasteland as a pack of gun-toting raptors wasn't awesome enough, modder Lurch of the L4DMaps community offers the Stay Puft mod which replaces Left 4 Dead 2's burly Tank with the soft and tasty juggernaut from Ghostbusters.

It's a pretty basic mod—a simple reskin of the Tank is all you'll get for less than a megabyte's download. Some default animations don't exactly translate well in those rolls of sugary goodness, as the model's arms stick out awkwardly and ragdoll effects are anything but smooth. Rock tosses are subsequently hilarious-looking. (You'll see what I mean in the short video I recorded above.) Still, making the conscious decision to shoot at and be chased by a grunting behemoth of marshmallow should count for something.

You can pick up Puft at L4DMaps' website. Be sure to also check out Left 4 Dead 2's freshly launched Steam Workshop listing for more mods.

Mod authors continue to add content to the Workshop, so keep coming back and checking to see what’s new. You can download the Workshop items automatically by clicking subscribe. This will also keep that item automatically up to date!

If you don’t see the add-on choice on the main menu – remove any hud or UI addons you are currently running; they may not have changed for the new layout. If you are downloading a campaign, make sure to check to see if it is in a collection which requires you to download all the elements in that collection. A good example is for Warcelona you need to go to <a href='http://steamcommunity.com/sharedfiles/filedetails/?id=121787087'>this page</a> and download all three parts.

We have currently removed all community created campaigns from our official servers as the authors move them to the Workshop. We will be restoring them with the new versions and featuring new Campaigns starting next week. We have the first few lined up and then will begin taking suggestions from the community.

Lastly and most importantly, today we are updating the Mac client for L4D2 to resolve issues Mac players are seeing with the Workshop. If you are on a Mac, it’s time to join in the fun and start grabbing some great skins, campaigns, and more.

We are working on the Mac Client issue this morning and investigating reports of Window server crashes.

A few notes.If you are trying a campaign in any gamemode and having issues connecting to a dedicated server, try to play locally. If it works locally, contact your server operator and ask them to update.

We will be removing all of the community campaigns we host on our servers and refresh them with the versions on the Workshop as they become available.

DO NOT UPLOAD CONTENT TO THE WORKSHOP THAT IS NOT YOURS!If you do, the content will be removed and you will get a temporary community ban.

Please use the reporting tool to report any upload violating the Steam Terms of Service. You do not need to report how much that mod kicks ass.

Valve just recently moved Steam Workshop out of beta, and we're already seeing a ton of great mods ready for your clicking.

We've had access to mods before, that's nothing new. But Valve's Steam Workshop completely streamlines the process of adding them in, making the ability to have smarter AI, new weapons and newly skinned enemies an easier process than ever before. And databased, too!

So what's out there now, roughly four days after its official release? Here are a few that caught my eye.

Playing as friggin' velociraptors

A Crash Bandicoot map

Warrior Bug enemies

A super-sexy Coach in formal wear

Team Fortress 2's Scout as a Hunter

The Gabe Newell of Boomers

There are a ton of other maps, skins for the four playable characters, skins for enemies, heck, skins for the defibrillator and ammo packs. There are weapons, from melee and assault rifles to machine guns and grenades. There are menu tweaks and UI changes. New soundtracks and sound effects. Just a metric crapton of things you probably don't need but, hey, you can download now.

Valve have posted a patch for Left 4 Dead 2 this morning. Along with the regular old incomprehensible patch notes, ("Cleaned up DLC add-on file dependencies and simplified talker file structure." Huh?) they've finally enabled Steam Workshop support, creating an easy system for browsing and installing new weapons, campaigns, items and - er - clothing. I guess the Venn diagram of fashion enthusiasts and mod creators does have some crossover.

As it's only been live for a few hours, L4D2's Workshop listing is still a bit barren. It shouldn't take long for some top content to appear, though - Left 4 Dead 2 already has a healthy modding community, so, with any luck, some of the best will be uploaded in the coming days.

Adding mods to the game was already a relatively simple process, but of course the Workshop streamlines it down further and, perhaps more importantly, will automatically each mod with any patch the creator uploads.

Hopefully we'll soon see some of the great community created campaigns start to appear, like these brilliant Back 2 School maps.

Content creators have been hard at work creating content for L4D2 but they have just gotten access to the new Workshop, so give them some time to upload their work.

To help other players find the coolest content, make sure to rate and discuss the submissions. We will be featuring submissions on l4d.com

To add content to L4D2:Load up Left 4 Dead 2 (or browse to it here). In game, click on the add-ons section from the main menu. There you can see add-ons once they are downloaded or choose browse the Workshop. Go into the Workshop, find a something you like – let’s say a skin for Francis where he is in a cop outfit. Click the subscribe button and it will automatically download and appear in the list. If you are doing this through the web browser, it will appear next time you start the game.

Please note – the Workshop has increased its file size limit to 200MB. But this still means some of the larger campaigns will be broken up into sub-200mb chunks. Those campaigns will be in collections and you will need to subscribe to the collection to get all the files.

To create and share content in L4D2:You will need to update your Authoring Tools and run the Workshop Manager in the tools to upload your content to the Workshop.

A great tip from GShock:If your campaign is over 200MB you will need to split your vpk into parts with content in each part.

This will also allow you to update your content a lot faster and in turn users do not have to download a much larger file when you release an update to a part.

Once this is done add all your items into a collection and mark it as a "items that work together (will show a 'subscribe to all' button)"

For both consumers and developers, there is a new forum – the Workshop discussion forum. Here you can discuss using the Workshop and report any bugs you are encountering. Each item in the Workshop has its own area to discuss that item.
